- 'Be it known thatLEDWARD @.Dtiienxenao, a citizen of the United States, residing at Honolulu,Island of Oahu, Territory of Hawaihhave invented a new and useful Atomizer for Liquid Fuel, of which the following is a specilication. Y Y

My invention relates to that claas of burners for liquid Vfuel which atomize the fuel previons to its entering the furnace.

The invention Ofburners employing the injector principle to draw in air and oil or other but they do not meet all the requirements for the reason that the fuel is either imperfectljv atomized Vor if accomplished the amount of steam used to operate the apparatus is too My invention employs a steam-injector to draw in air and impart to the steam and air mixture a velocity. as it entere the mixingchamber through an orifice, all being arranged such that the liquid fuel is drawn into and atomized in said mixing-chamber and is then ejected through another orifice into the furnace. 'Iheproportion of steam, air, and fuel is adjustabljv controlled, as will hereinafter more fully appear. The accompanying drawing represents in section an atomizer for liquid fuel eml'iodjing my invention.

The casing n preferably4 a casting. at one end has an air-inlet c and an air-chamber fl, provided with an adjustably-connected steaminjector (l, with a conical orifice 4Z. At the other end of the casing a is the mixing-chamber e', provided with a liquid-fuel inlet /z and a plug fl, having an orilice j to the furnace or ber 7J and the mixing-chamber e is located a steam and air chamber g, which connects with the air-chamber 6 by the passage and with the mixing-chamber z: by the orifice f.. it will now be noted that the steam-inlet is arranged to form an injector, the amount of air being drawn in being regulated b5' adjustment -of the position of the steam-inlet nozzle with respect Vto the casing-passage rl`he Steam and the orlicef under a high velocity,enteringthe mixing-chaml'ier On account of the contial vacuum is formed at the edge of the chamber 3., due to'ivhich the liquid fuel is drawn in from the supply-pipe /i' and becomes atomized and is ejected through the orifice j. The flame beginsimmcdiately outside of the plug The amount of steam admitted is regulated by a valve in the steam-supply pipe connected to the steam-inlet. The liquid fuel-such as crude oil, petroleum, tar,molaeses,&c.-is also regulated a valve. rlhe plug is removable for cleaning.

Having described my invention, what l claim, and desire to secure by Letters Patent,

is-- -Y l. .ein atomizer for liquid fuel, comprising a casing" provided With an airchamber, a steam-injector for drawing air into said chamloer,` a mixing-chamber having a fuel-inlet, a plug in the end of said. casing provided with a conetrcted outlet to the furnace in axial alinement with the casing and a constricted passage bet-Ween the air-chamber and the mixing-chamber to impart a high velocity to the air and steam entering said mixing-chamber. 2. )in atomizer for liquid fuel, comprising a casing provided with an air-chan'iber, a

steam-injector for drawing air into said chamber, an enlarged air and steam chamber, a mixing-chamber bevond the latter and provided with a fuel-inlet and a constricted burneroutlet inv axial aliuement with the casing leading to the furnace` and a constricted passage Abetween the air and steam chamber and the iiiixing-chamber, to imparta high velocity to the air and steam entering thc mixing-charnber. l

An atomizer for liquid fuel, comprising the casing u, having' the airfch'amber provided with the inlet c, the steani-injector (Z entering said air-chamber; the air and Steam chamber r/` the passage I connect-ing the chambers and (/,i the mixing-chamber e nconnected to the chamber .g5-'the fuel-supply /t enter-lng said chamber fand the .outlet-plug having aY conetrictcdforifice j.

in' testimoniT whereof l have signed my name to this specification in the presence of two subscribing witnesses.
